Given numbers are 714, 172, 618, 661
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(714, 172) = 61404
GCD(714, 172) = ( 714 x 172 ) / 61404
= 714 / 172
= 714
Step2:
LCM(2, 618) = 618
GCD(2, 618) = ( 2 x 618 ) / 618
= 2 / 618
= 2
Step3:
LCM(2, 661) = 1322
GCD(2, 661) = ( 2 x 661 ) / 1322
= 2 / 661
= 2
So, Greatest Common Divisor of 714, 172, 618, 661 is 1
